Nickel
is a hard, malleable, ductile, lustrous, silvery white,
ferromagnetic metallic element in Group VIII of periodic
table; atomic number 28; atomic mass 58.69; melting
point ca 1,453°C; boiling point ca 2,732°C;
specific gravity 8.902 g/cm3; valence 0, 1, 2, 3; electronic
config. 2-1 or 4s 23ds8. It is a fairly good conductor
of heat and electricity. It takes on a high polish.
Its magnetic properties and chemical activity resemble
iron and cobalt. It has properties to form easily a
number of alloys. Some of the metals that nickel can
be combined with are iron, copper, chromium, and
zinc. Most of these nickel compounds have blue or green
color. Nickel dissolves in dilute acids slowly but will
be passive with nitric acid like iron. Fine nickel powder
adsorbs hydrogen and is in the hydrogenation of oils.
Nickel alloys are used in making coins and heat exchange
items like valve. The Most of nickel is used to make
stainless steel as a protective and ornamental coating
for less corrosion. Nickel is combined with many other
elements, including chlorine, sulfur, and oxygen.
Most of these nickel compounds dissolve easily in water
and have a characteristic green or blue color with no
characteristic odor or taste. Nickel compounds are used
in plating, coloring ceramics, making some batteries,
and as chemical reaction catalysts.
